Close up (macro) photos of wood texture at Coyote Hills Regional Park. The regional park is
full of structures made of wood. One can make a fascinating series of photos studying the
texture and fibers of different kinds of wood. Presence of a knot in the wood make it
even more interesting, as you seein the bottomright photo. These are "processed" wood,
machined etc. Another topic is the texture and variety of wood in living trees.
